PRINTING-PRESS FOR PRINTING ADDRESSES.

SPECIFICATION forming part of Letters Patent No. 436,631, dated September 16, 1890.

Application filed January 27, 1890. Serial No. 338,189. (No model.)

To all whom it may concern.-

Be it known that I, HUGO LEWINSOHN, a subject of the King of Prussia, residing at Bromberg, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Printing- Presses for Printing Addresses, of'which the following is a full, clear, and exact specification.

This invention relates to printing machines such as are used for printing addresses or other matter upon envelopes, wrappers, and parcels, and for other like purposes; and it consists in the construction, arrangement, and combinations of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation, partly in section, of a printing-press constructed in accordance with this invention. Fig. 2 is a plan view of the same; and Figs. 3, 4, 5, and 6 are detail views hereinafter explained.

Upon a stand or frame a at the rear of the press is mounted an angular lever 1), connected by a link 0 to a platen d, pivoted at its lower end to the base of the press-frame. I do not, however, limit myself to the use of the lever 12, as said lever may be substituted by an eccentric supported by a suitable frame at the rear of the press, as shown in dotted lines in Fig. 1, and connected by a rod or by the link a to the platen, or, instead of both the lever and eccentric, the platen may be.

provided with a handle, as shown in dotted lines in Fig. 1, so that the platen may be operated directly by hand. A spring-pawl 6' (shown best in Figs. 5 and 6) is secured at one end to the platen and is provided at its other end with a hook 6', adjustable thereon and held in place by a suitable set-screw. Said hook is adapted to slide upon and engage the points of a series of spirally-arranged segmental teeth It on the outer face of a disk f, fixed on a transverse shaft 2', journaled in the press -frame. By this arrangement of parts the reciprocation of the platen involves Upon the shaft 1'' in rear of the table 0 of p the press is fixed a polygonal roller 2', in each of the angles of which is fixed a tooth is, as shown inFigs. 3 and 4E. The teeth h on the disk f are so arranged that their points will coincide with the angles of said roller, the number of such teeth corresponding to the number of angles of the roller. The rollerz'is adapted to drive a band or strip of cloth or other suitable material a, or it may be a chain, upon which the different stereotypes, blocks, rubber stamps, or other printing-surfaces are secured in any proper manner at equal distances apart, according to the dimensions of the roller 1'. Said band or strip is wound normally upon a roller A, j ournaled in the upper front end of the press-frame, beneath which roller near the base of said frame is journaled in like manner a similar roller B, upon which said band or strip is adapted to be wound after the printing-sun faces have been utilized, a pulley on the shaft of said roller being connected by a belt with a pulley on the shaft 2', as shown in Fig. 2.

An ink or color fount y is mounted in the usual manner upon the press, from which the ink or color is led and applied to the printing-surfaces byupper and lower distributingrollers Z and m and inking-rollers n and n, as shown in Fig. 1.

Upon the rear left-hand end of the press are formed or secured aligning keepers, in which is adapted to slide a rod 8, a portion of which between the keepers is reduced in diameter and encircled by a spring 25,v secured at its rear end to the press and at its forward end to the rear face of the forward enlarged .end of said rod, the front face of which end is beveled downwardly and forwardly. The rear enlarged end of said rod projects normally beyond its keeper, and is adapted to be impinged upon by the platen as the latter is moved forward.

One end of the shaft of the distributingroller Z is journaled at one end in the forward end of an arm a, the rear end of which is beveled upwardly and rearwardly and rests normally upon the beveled end of the rod 3, as shown in Figs. 1 and 2. Said arm a near its rear end'is provided with a stud to which is fastened one end of a spring as, which bears with its free end on a pawl z, pivoted to the arm a and engaging a ratchet-wheel w on the shaft of the roller Z next said arm.

Beneath the table 0 of the press are journaled transverse shafts carrying, respectively, rotary brushes p, q, and r, the office of which is to thoroughly cleanse the printingsurfaces after they have been used. To this end the brush p revolves in a trough 19', containing an alkaline or other suitable similar cleansing solution, and the brush q revolves in a trough q, containing water or other rinsing-liquid. The brush 1 revolves in the air and serves to dry the printing-surfaces after they have been cleansed and rinsed.

In operation the strip or band a is drawn from the roller A, passed over the table of the press, and its end engaged with the teeth of the roller-1}. As the platen is reciprocated by the means shown and described, or by hand, the hook of the spring-pawl e, sliding over and acting upon the points of the teeth of the disk f, causes the roller 7; to rotate and present the printing-surfaces successively for imprint upon the paper or other material held temporarily upon or carried in the usual manner by the platen. In the forward movement of the platen it impinges upon the rod 8, and through the same and the arm it causes the pawl z to turn the ratchet of the roller Z the space of one tooth, thus insuring a uniform feed from the fount y to the printing-surfaces, the spring 25 reacting as the platen is carried rearwardly to retract the rod 8 and consequently the arm it. As the printing-surfaces are successively used they are carried be-- neath the table 0 over the brushes p, q, and r, by Which they are cleansed and dried, and the end of the strip or band a is led and conneeted in any proper manner to the roller B, the subsequent rotation of the shaft 2" causing the same to be wound upon said roller.

When a chain is used instead of the band or strip a, the teeth is on the roller '5 are arranged to take into the links of said chain.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the frame, horizontal table 0, the rollers A B at the rear thereof, the roller at the front end of the table, and the printing-band passing along the table around the latter roller and connected at its ends to rollers A B, and the verticallyswinging platen d, pivoted at its lower end to the frontend of the frame, of the longitudinally-slidin g rod 3, mounted on the frame and projecting beyond the front end thereof into the path of the platen in its inward throw, the inking-rolls under which the printing band or belt passes, an ink-distributing roller therefor provided with a ratchet, a verticallyswinging arm it, acted upon at its forward end by the inner end of the rod 3 in the inward movement thereof, and provided with a pawl engaging the said ratchet to rotate the distributing-roll, substantially as set forth.

2. The combination, with the frame, the horizontal table, the shaft at the front end thereof having a roller, aplaten, the upper and lower rollers A B, the printing-belt passing along the upper and lower sides of the table around the roller at the front end thereof and connected at its ends to the rollers A B, and means for operating the printing-belt, of a cleaning mechanism comprising two troughs p q under the table and each havingabrush engaging the lower side of the printing band or belt, and a brush 1* in rear of the cleaning-brushes for drying the Washed portion of the printing band or belt, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

HUGO LEWINSOHN.
